Description

=begin
This problem was originally reported to vim-jp project. See
((URL:https://github.com/vim-jp/issues/issues/372)) (Japanese discussion).

(()) is an text editor and it supports embedded
ruby interface so that we can customize Vim with Ruby. On Mac, ruby
causes crash.

Steps to reproduce:
$ vim
:function! F()
: ruby nil
:endfunction
:call F()
:ruby 10000.times { 'x' * 10000 }
Vim: Caught deadly signal ABRT
Vim: Finished.

Version is:
Mac OS X 10.7.5
ruby-2.0.0-p0
Vim 7.3.918

Maybe the following is minimum C code to reproduce crash.

/* rubyembed.c */
#include

void rbinit() {
int dummy_argc = 2;
char *dummy_argv[] = {"foo", "-e0"};
RUBY_INIT_STACK;
ruby_init();
ruby_process_options(dummy_argc, dummy_argv);
}

void rbexe(const char *src) {
int state;
rb_eval_string_protect(src, &state);
if (state)
ruby_error_print();
}

void init() {
int eatstack[1024]; /* perhaps you need more to crash */
rbinit();
}

int main(int argc, char **argv) {
init();
rbexe("10000.times { 'x' * 10000 }");
return 0;
}

[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

I am not sure that this is correct fix but above problem seems
disappeared with this.

Or perhaps such code is not valid or something is wrong in Vim's if_ruby code?
